The origin story could have given more of his childhood/youth, back story, like Negan in "Here's Negan." Although we know a lot more throughout the series, I would have enjoyed seeing his father and family interactions (what happened to his mom?) All TWD did was narrate (through Norman Reedus), the story of Daryl we have already seen. Clarification of Daryl's feelings and growth was good. I suppose I was looking for something I didn't already know.
